ABSTRACT

Methods for providing a location of an object or objects of interest that may be performed by a processor of a computing device may include generating a map of an environment around the computing device by a first simultaneous location and mapping (SLAM) operation using information received from the optical sensor, identifying an object of interest in the environment of the computing device by an object recognition operation using information received from the optical sensor, determining a location of the object or objects of interest in the environment, and presenting the determined location of the object or objects of interest in the environment in response to a trigger event correlated to the object or objects of interest.

BACKGROUND

The pace of modem life is hectic and distracting. People often forget things at home or the office, such as keys, wallets, phones, ID badges, etc. Objects also get misplaced at home, such as remote controls. Time is wasted looking for such objects or returning to where they were left behind.

Fifth-generation New Radio (5GNR) systems provide support for services for wearable devices such as Head Mounted Displays (HMDs), such as smart glasses, Virtual Reality (VR) devices, Extended Reality (XR) devices, and the like. Some HMDs are configured with externally-facing cameras to record the environment around the user. Some HMDs may include up to six such cameras, enabling the HMD to record nearly 360 degrees around the wearer.

DETAILED DESCRIPTION

Various embodiments will be described in detail with reference to the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. References made to particular examples and embodiments are for illustrative purposes, and are not intended to limit the scope of the claims.

Various embodiments include methods that may be implemented on a processor of a computing device for providing a user with information (e.g., guidance to) the location of an object or objects of interest. In various embodiments, the computing device may be configured with an optical sensor (e.g., a camera). Various embodiments may use machine perception and recognition of objects within images gathered by the optical sensor of the computing device to locate an object or objects of interest within a map of the surroundings generated using SLAM techniques. The locations of objects of interest may be recorded in memory by the computing device (or a connected system). In response to a request for the location of the object or objects of interest, the computing device may recall the last known location of an object or objects of interest from memory, and provide the object’s last known location to the user within the map in a manner that aids the user in finding the object, such as in images (e.g., an arrow or path) and/or numbers or text (e.g., a distance to the object or objects) presented in a head-mounted display or smart-glasses.

As used herein, the term “computing device” refers to an electronic device equipped with at least a processor, memory, and a device for presenting output such as a location of an object or objects of interest. In some embodiments, a computing device may include wireless communication devices such as a transceiver and antenna configured to communicate with wireless communication networks. In some embodiments, a computing device may be wearable by a person. A computing device may include any one or all of smart glasses, augmented/virtual reality devices, cellular telephones, smartphones, portable computing devices, personal or mobile multi-media players, laptop computers, tablet computers, 2-in-1 laptop/table computers, smart-books, ultrabooks, multimedia Internet-enabled cellular telephones, wearable devices including smart-watches and smart-contact lenses, entertainment devices (e.g., wireless gaming controllers, music and video players, satellite radios, etc.), and similar electronic devices that include a memory, wireless communication components and a programmable processor. As used herein, the term “smart” in conjunction with a device, refers to a device that includes a processor for automatic operation, for collecting and/or processing of data, and/or may be programmed to perform all or a portion of the operations described with regard to various embodiments. For example, a smart-phone, smart-glasses, smart-contact lenses, smart-watch, smart-ring, smart-necklace, smart-cup, smart-straw, smart-appliances, etc.

The term “system on chip” (SOC) is used herein to refer to a single integrated circuit (IC) chip that contains multiple resources and/or processors integrated on a single substrate. A single SOC may contain circuitry for digital, analog, mixed-signal, and radio-frequency functions. A single SOC may also include any number of general purpose and/or specialized processors (digital signal processors, modem processors, video processors, etc.), memory blocks (e.g., ROM, RAM, Flash, etc.), and resources (e.g., timers, voltage regulators, oscillators, etc.). SOCs may also include software for controlling the integrated resources and processors, as well as for controlling peripheral devices.

The term “system in a package” (SIP) may be used herein to refer to a single module or package that contains multiple resources, computational units, cores and/or processors on two or more IC chips, substrates, or SOCs. For example, a SIP may include a single substrate on which multiple IC chips or semiconductor dies are stacked in a vertical configuration. Similarly, the SIP may include one or more multi-chip modules (MCMs) on which multiple ICs or semiconductor dies are packaged into a unifying substrate. A SIP may also include multiple independent SOCs coupled together via high speed communication circuitry and packaged in close proximity, such as on a single motherboard or in a single wireless device. The proximity of the SOCs facilitates high speed communications and the sharing of memory and resources.

As used herein, the terms “component,” “system,” “unit,” “module,” and the like include a computer-related entity, such as, but not limited to, hardware, firmware, a combination of hardware and software, software, or software in execution, which are configured to perform particular operations or functions. For example, a component may be, but is not limited to, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, and/or a computer. By way of illustration, both an application running on a communication device and the communication device may be referred to as a component. One or more components may reside within a process and/or thread of execution and a component may be localized on one processor or core and/or distributed between two or more processors or cores. In addition, these components may execute from various non-transitory computer readable media having various instructions and/or data structures stored thereon. Components may communicate by way of local and/or remote processes, function or procedure calls, electronic signals, data packets, memory read/writes, and other known computer, processor, and/or process related communication methodologies.

People may forget or misplace things at home or the office. Time is wasted looking for such objects or returning to where they were left behind. Various embodiments enable a computing device, such as a Head Mounted Display (HMD), smart glasses, etc. to employ machine perception of images gathered by an optical sensor (e.g., a camera) of the computing device to enable the locating of an object or objects of interest (e.g., a forgotten or lost item). Various embodiments enable a computing device to generate a map of an environment around the computing device by employing a first simultaneous location and mapping (SLAM) operation using information received from the optical sensor. In some embodiments, the computing device may perform the SLAM operation to identify features of the environment around the computing device from the information received from the optical sensor and determine a position of the identified features. It will be understood that references to “a SLAM operation” include one or more steps, processes, operations, computations, and/or the like, and is not a limitation to a single step, process, operation, computation, etc.

In various embodiments, the computing device may identify an object or objects of interest in the environment of the computing device by an object recognition operation using information received from the optical sensor. In some embodiments, the computing device may identify the object or objects of interest while identifying features of the environment around the computing device from the information received from the optical sensor and determining positions of the identified features to generate a map using SLAM processes, thereby locating a recognized object within the SLAM-generated map. In some embodiments, the computing device may provide an output indicating the identification of one or more objects of interest (e.g., highlighting the object or objects of interest in a display device, drawing a rectangle or circle around of the object or objects of interest in an augmented reality display of a head-mounted device, and the like). In some embodiments, the location of one or more objects of interest may be correlated to a particular grid or mesh location within a map of the environment, with the grid or mesh location used to indicate the location of the objects of interest.

In some embodiments, the computing device may receive an input from a user to trigger a scanning process to identify an object or objects of interest. Some embodiments may utilize a trained neural network to perform object identification or object recognition operations. In some embodiments, the computing device may apply images of objects identified in the environment of the computing device to a trained neural network configured to provide as an output identifications of objects of interest. In such embodiments, the computing device may determine a location in the environment of the object or objects of interest provided as output by the trained neural network during a SLAM operation. Examples of neural networks that may be used for object recognition include Region-Based Convolutional Neural Network (R-CNN), Fast R-CNN, Faster R-CNN, Histogram of Oriented Gradients (HOG), Region-Based Fully Convolutional Network (R-FCN), Single Shot Detector (SSD), Spatial Pyramid Pooling (SPP-net), and YOLO (You Only Look Once).

In some embodiments, the computing device may receive an input from a user to confirm an identification of an object or objects of interest made by the computing device. For example, the computing device may highlight a potential object of interest that the computing device has identified (e.g., a TV remote control). The computing device may receive an input (e.g., a button press, a gestural command, etc.) to confirm that the highlighted object is an object of interest. Similarly, the computing device may receive an input indicating that the highlighted object is not an object of interest.

In some embodiments, the computing device may determine a location of the object or objects of interest in the environment using a second SLAM operation. In some embodiments, the computing device may assign to the object or objects of interest coordinates within the map generated by the first SLAM operation, such as the operations performed by the computing device to generate the map of the environment around the computing device. In some embodiments, the computing device may assign to the object or objects of interest a grid or mesh location within the map generated by the first SLAM operation.

In some embodiments, the computing device may present the determined location of the object or objects of interest in the environment in response to a trigger event such as a user request for the location of the object or objects of interest. In some embodiments, the computing device may present an image on a head-mounted display, such as smart glasses, of the object or objects of interest at the determined location within a map of the environment determined by the SLAM operations. For example, the computing device may present a most recent image (e.g., a photo) of the object or objects of interest at the determined location within a map determined using SLAM methods. In some embodiments, the image of the object or objects of interest at the determined location may include a recent image (e.g., a most recent image) of the object or objects of interest obtained during or as a result of an object recognition operation performed by the computing device. In some embodiments, the computing device may present a representation of the map generated using the first SLAM operation that includes an indication (e.g., a highlight, a star, a blue dot, etc.) of the location of the object or objects of interest. In some embodiments, the computing device may present a grid or mesh representation of the map generated using the first SLAM operation, and indicate the location the object or objects of interest in the form of a highlighted grid or mesh location within the displayed map. In some embodiments, the computing device may use a sound output device (e.g., a speaker) to produce an audible indication of the location of the object or objects of interest (e.g., “your keys are on the counter next to the flowerpot”).

In some embodiments, the computing device may generate a direction or navigation path from a current location of the computing device to the location of the object or objects of interest within the map generated by the first SLAM operation. In some embodiments, the computing device may output the generated navigation path for user on a display device (e.g., as a map or navigation path), via a sound output device (e.g., as a step or series of steps to move from the computing device’s current location to be location of the object or objects of interest), etc. In some embodiments, the computing device may render on a display device of the computing device (e.g., display of smart glasses or an HMD) an indication, such as an arrow or similar pointing icon, of the direction from the computing device to the location of the object or objects of interest. In some embodiments, the computing device may determine the distance to the location of the object or objects of interest from the location of the computing device, and present the distance to the user, such as in the form of a number and/or text presented on a display of the computing device (e.g., display of smart glasses or an HMD).

The computing device may present the determined location of the object or objects of interest in the environment in response to a trigger event for presenting the location of the object or objects of interest. In some embodiments, the trigger event or user request for the location of the object or objects of interest may include a user input (e.g., a button push, touch screen interaction and/or verbal command or query) received by the computing device requesting the location of the object or objects of interest. In some embodiments, such input may include a query, a command, an instruction, etc. received by the computing device verbally, via a gestural command, or through any manner of input device. Other trigger events described in more detail herein include recognition of a user behavior or action correlated to a specific object or objects of interest, recognition of a user behavior or action correlated to a specific object or objects of interest and to other conditions (e.g., time of day, day of week, weather conditions, etc.), and/or recognition of a user behavior or action correlated to a specific object or objects of interest (and optionally other conditions) and determination that one or more of the correlated objects of interest are not with the user.

In some embodiments, the computing device may correlate the location of the object or objects of interest in the environment (determined by a SLAM operation) with a user action or behavior. In such embodiments, the trigger event may include detecting an occurrence of user action or behavior indicative or suggestive that the user should be reminded or directed to an object or objects of interest. For example, using a machine learning algorithm, the computing device may correlate a location of a TV remote control with a user behavior of sitting down in front of a television. In response to detecting or determining that the user has sat down in front of the television, the computing device may present the location of the TV remote via an output device (e.g., a display, a speaker, etc.) of the computing device.

In some embodiments, the computing device may correlate one or more objects of interest with a user action or behavior and inform the user about the location of one or more of the objects in the environment (determined by a SLAM operation) if such objects are not with or near the user. In such embodiments, the trigger event may include detecting a user an object, determine whether the location of the object as determined by SLAM and the user are in separate locations, and if so, display and/or sound a reminder informing the user where to find the correlated objects of interest. As an example, the computing device may correlate a user behavior of approaching the user’s vehicle with keys for the vehicle, and determine the location of the keys for the vehicle in response to the user approaching the vehicle. In response to determining or detecting that the user is approaching the vehicle but the keys are in a different location, the computing device may display the location of the vehicle keys to the user via an output device (e.g., images presented on smart-glasses).

In some embodiments, the computing device may correlate a user behavior to a plurality of obj ects, all of which the user typically uses together while performing the behavior. For example, the computing device may correlate the user approaching the user’s vehicle with possession by the user of car keys, a wallet and/or purse of the user, and corrective vision glasses, determine whether any of these correlated objects are not with the user, and display and/or sound a reminder informing the user about the location of any of the correlated objects that is not with the user. As an example, the computing device may correlate a user behavior of approaching the user’s motorcycle with a motorcycle key chain, the user’s helmet, and the user’s driving jacket, determine whether any of these correlated objects are not with the user, and display and/or sound a reminder informing the user about the location of any of these correlated objects that is not with the user.

In some embodiments, the trigger event may include a time trigger or a date trigger. In various embodiments, the computing device may determine a correlation between a time trigger and/or a date trigger and an object or objects of interest by using a machine learning algorithm, based on user input, or another suitable input or indication to determine such a correlation. For example, the computing device may correlate a time (e.g., 7:30 AM) with one or more objects of interest (e.g., a briefcase, a smartphone, car keys, etc.), such as objects that a user may typically take to work at that time. In some embodiments, in response to the time trigger, the computing device may present the location of the object(s) of interest. As another example, the computing device may correlate a date (e.g., a person’s birthday) with an object or objects of interest (such as a present purchased for the person’s birthday). In some embodiments, in response to the date trigger, the computing device may display the location of the object(s) of interest to the user via an output device (e.g., images presented on smart-glasses).

In some embodiments, the computing device may correlate an object or objects of interest with a plurality of context information (such as a user behavior or action), and a time of day, a date, weather information, and/or the like. In such embodiments, the computing device may correlate different objects of interest with various user behaviors or actions at various times, dates, environmental conditions, etc. For example, the computing device may correlate a briefcase with a user action of approaching the user’s vehicle at 7:30 AM on a weekday, and recognize a trigger event to present the location of the briefcase in response to detecting the user approaching the vehicle in conjunction with the time being approximately 7:30 AM. As another example, the computing device may correlate a tennis racket with a user action of approaching the user’s vehicle (i.e., a similar user action) at 2:00 PM on a Sunday (i.e., a different day and/or time), and recognize a trigger event to present the location of the tennis racket in response to detecting the user approaching the vehicle in conjunction with the time being approximately 2:00 PM on a Sunday. As another example, the computing device may correlate a location of an umbrella with a time and a date (e.g., 7:00 AM on a weekday) and a weather condition (e.g., rain), and recognize a trigger event to present the location of the umbrella in response to the time approaching 7:00 AM on a weekday in conjunction with the correlated weather condition (e.g., rain). In various embodiments, the computing device may receive information to perform such correlations from, for example, a network element, server, etc. As mentioned above, in some embodiments, the computing device may correlate a plurality of objects with a given user behavior at or under particular times, dates, environmental conditions, and recognize a triggering event in response to the location of any of the correlated objects differing from the user’s location at the correlated time, date and/or environmental condition. For example, the computing device may correlate a location of the user’s briefcase, car keys, and reading glasses with the user approaching the user’s vehicle at 7:30 AM on a weekday, so that the computing device recognizes a trigger event to present a location reminder if any of these objects are not with the user when the user approaches the vehicle at the correlated time.

In some embodiments, the computing device may operate as part of a system including a plurality of computing devices configured to provide and/or obtain updated locations of objects of interest. For example, two or more computing devices operating in an environment may communicate with each other to provide updated location information for object or objects of interest. As another example, computing devices may communicate with a local network device (e.g., a local server), a remote network device (e.g., a cloud server), or another suitable device, to provide updated locations of objects of interest. In this manner, in some embodiments, a computing device may receive an indication from another (a second) computing device that an object or objects of interest has been relocated to a second location in the environment. In various embodiments, the indication that the object or objects of interest has been relocated to a second location in the environment may be communicated directly to the first computing device by the second computing device, or via an intermediary device, such as a network device, server, etc. The first computing device may present the second location of the object or objects of interest in the map generated by the first SLAM operation in response to a trigger event.

For example, a first computing device may determine that a first user put her car keys (designated as an object or objects of interest) down in a first location in the user’s house. Later, a second computing device (e.g., operated or worn by a second user) performing SLAM operations to map rooms in the house may recognize the car keys and, in identify the location of the car keys in the map, determine that the car keys have been moved to a second location (e.g., the second user picked up and moved the keys). In response to determining the occurrence of a trigger event (e.g., a time trigger, such as 7:30 AM), the first computing device may query a map database accessible to both the first and second computing to determine the current location of the car keys, and then display the second location (i.e., the current location or the last-known location) of the car keys (the object or objects of interest) in the map generated by the SLAM operations. In various embodiments, the first computing device may receive an indication that the object or objects of interest has been relocated to the second location in the environment via a “push” operation, a “pull” operation (e.g., in response to a request for the location of the object or objects of interest), or another suitable operation.

Some embodiments may enable a function by which a computing device is not authorized to disclose a location of an object or objects of interest, such as for privacy purposes, to enable parental controls, and other suitable functions. For example, a parent may hide an object from a child, such as a TV remote, candy, etc. As another example, a roommate may desire to make the location of certain objects unobtainable by another roommate. As another example, a worker may wish to distinguish personal items (for which the location is unobtainable by coworkers) from items for work (for which the location is obtainable by coworkers). In such embodiments, the computing device and/or a network element may store an indication that another computing device is not authorized to disclose the location of the object or objects of interest. Based on such an indication, a computing device may be prevented from obtaining the location of the object and/or prevented from disclosing the location of the object. In some embodiments, in response to the occurrence of a trigger event (e.g., a request to locate the object or objects of interest), a computing device may determine whether the computing devices authorized to disclose the location of the object or objects of interest., and present the location of the object or objects of interest within the map generated by the first SLAM operation in response to determining that the computing device is authorized to disclose the location of the object or objects of interest, the computing device may. In response to determining that the computing device is not authorized to disclose the location of the object or objects of interest, the computing device may present an indication that the computing device is not authorized to disclose the location of the object or objects of interest.

As an example of an implementation of various embodiments, a user may initialize his computing device (e.g., an HMD) to recognize an object or objects of interest (e.g., car keys, wallet, etc.) in video images captured by a camera on the computing device. The computing device may use a trained machine learning model to learn to recognize the object or objects of interest. The computing device may perform SLAM operations to localize the computing device in the environment (e.g., within a room), and to locate the object or objects of interest in environment as determined by SLAM operations. In some embodiments, the computing device may assign coordinates to the object or objects of interest (e.g., within a map generated by the first SLAM operation). The computing device may store the assigned coordinates in memory, and may use the assigned coordinates to support locating the object or objects of interest in the future. The memory may be within the computing device and/or may be a remote memory (e.g., in a remote server) accessible by the computing device. In some embodiments, the computing device may reduce an amount of information stored by saving an image of the object or objects of interest (or a frame containing the image) and its last known coordinates, rather than storing numerous images or large video data files. In response to a trigger event or a user request for the location of the object or objects of interest, the computing device may present the location of the object or objects of interest using, for example, the stored coordinates within the SLAM-generated map, such as displaying an image or indicator of the object or objects of interest in a head-mounted display of the SLAM-generated map.

As another example of an implementation of various embodiments, a user’s computing device (e.g., an HMD) may learn (e.g., by the operations of a machine learning algorithm) objects that the user typically carries or travels with, such as a laptop bag, jacket, keys, wallet, smartphone, etc. In some aspects, the computing device may correlate these objects and one or more user activities, such as leaving home, leaving work, etc., and/or an approximate or precise time of day (e.g., morning, afternoon, 7:30 AM, 6:00 PM, etc.). In some implementations, the computing device may provide a reminder via a display device, a speaker, and/or the like, such as “did you forget your car keys?” or “your car keys are on the kitchen counter next to the plant.”

As another example of an implementation of various embodiments, a user’s computing device may recognize that the user has left a restaurant without his credit card. In some embodiments, the computing device may generate a map of the environment around the computing device (e.g., the restaurant) by a first SLAM operation using information received from the computing device’s optical sensor. Using information received from the optical sensor, the computing device may identify the credit card (an object or objects of interest) in the environment by an object recognition operation. By performing a second SLAM operation, the computing device may determine the location of the credit card (e.g., on the table next to a receipt for dinner). The computing device may determine a trigger event, such as approaching the user’s vehicle, leaving the restaurant, moving a threshold distance away from the credit card, and/or the like. In response to the trigger event, the computing device may present the location of the credit card on the table back at the restaurant.

As another example of an implementation of various embodiments, a user’s computing device may receive an input from a user setting a reminder for an object or objects of interest corresponding with a trigger event (e.g., a time trigger, an action such as the user leaving a location, etc.). For example, the computing device may receive an input setting a reminder such as “don’t forget the coupons for the grocery store trip at 3:00 PM.” The computing device may generate a map of the environment around the computing device by first SLAM operation (or may use an already-generated SLAM map), may identify the object or objects of interest (in this case, the coupons) using information received from the computing device’s optical sensor, and may determine a location of the object or objects of interest in the environment, such as in a second SLAM operation. In response to a trigger event (e.g., 3:00 PM, leaving the house, approaching the vehicle, etc.), the computing device may present the location of the object or objects of interest in the environment (e.g., the location of the coupons).

Various embodiments improve the utility and effectiveness of operations of computing devices by enabling computing devices to utilize SLAM operations to generate maps of an environment around the computing device and locate objects of interest in the environment. Various embodiments further improve the utility and effectiveness of operation of computing devices by enabling computing devices determine the occurrence of a trigger event and present the location of objects of interest in response to the trigger event.

With reference to FIG. 5B, following determination of a location of the object or objects of interest in the environment in block 506 of the method 500, in operations 500 b the processor may correlate the location of the object or objects of interest in the environment with a user action, a user behavior, or user location in block 510. For example, using a machine learning algorithm, the processor may correlate a location of a TV remote control with a user behavior of sitting down in front of a television. As another example, the computing device may correlate a user behavior of approaching the user’s vehicle with a location of the keys for the vehicle.

In some embodiments, in block 510 the processor may determine or generate complex correlations of the object or objects of interest with user behavior, actions or location using a variety of information regarding current conditions relevant to a user’s actions, behavior and/or location. In some embodiments, the processor may correlate an object or objects of interest with a user behavior, action and/or location as well as a time of day, and/or a date, and/or weather information, and/or other information. For example, the processor may correlate the user’s briefcase, car keys, and reading glasses with the user approaching the user’s vehicle at 7:30 AM on a weekday, so that the computing device can generate a location reminder if any of these objects are not with the user at that time.

In some embodiments, in block 510 the processor may correlate a location of the user with object or objects of interest. In some embodiments, the correlated user location may be in the form of a boundary or geofence around a certain location (e.g., the user’s home, workplace, etc.). For example, objects (e.g., house keys, wallet, etc.) that the user should have when leaving a location (e.g., the user’s home) may be correlated to a boundary or geofence around that location. As another example, objects that a user should have when entering a boundary or geofence around a certain location (e.g., the user’s workplace, a construction site, etc.). In some embodiments, the correlated user location may be in the form of a distance to the object or objects of interest. For example, a user may correlate the user’s smartphone to a particular distance to ensure the user remains within hearing distance of the smartphone. In some embodiments, the processor may correlate an object or objects of interest with a detectable condition associated with a particular location, such as reception or strength of signals from a particular WiFi hotspot or router, a particular Bluetooth transceiver, a particular cell tower, etc. For example, a user may correlate the user’s smartphone with the user’s home WiFi router (e.g., a minimum strength of the WiFi signal from the home router) to ensure the user is reminded about the location of the user’s smartphone when approaching or moving beyond the user’s WiFi network.

Means for performing the operations of block 510 may include the processor (e.g., 210, 212, 214, 216, 218, 260, 312, 410) and the object location-trigger event correlation module 432.

In block 512, the processor may detect an occurrence of a correlated user action, behavior or location. For example, the processor may detect the user behavior of sitting down in front of the television, approaching the user’s vehicle, etc. In the case of complex correlations, the processor may detect an occurrence of a correlated user action or behavior at or in conjunction with occurrence of another correlated condition or conditions (e.g., time of day, day of week, weather conditions, etc.). In some embodiments, in block 512 the processor recognize when a correlated user location condition is satisfied. For example, if a location of the user has been correlated to the object or objects of interest, the processor may recognize and issue a trigger event when the user in possession of the computing device satisfies the correlated user location condition. In some embodiments, the user location condition may be in the form of a boundary or geofence in which the processor recognizes a trigger event when the user either leaves or enters the boundary or geofence. In some embodiments, the user location condition may be in the form of a distance to the object or objects of interest in which the processor recognizes a trigger event when the user either comes within the distance or travels beyond the distance to the object or objects of interest. In some embodiments, the user location condition may be a detectable condition associated with a particular location, such as reception or strength of signals from a particular WiFi hotspot or router, a particular Bluetooth transceiver, a particular cell tower, etc. For example, a user may correlate house keys and a wallet or purse to a boundary or geofence around the user’s house, and in block 512 the processor may recognize when the user approaches the boundary or geofence, causing the computing device to display locations of the house keys and wallet or purse in block 508 to help the user find those objects before leaving home. As another example, a user may correlate the user’s hardhat with a boundary or geofence around a construction site, and in block 512 the processor may recognize when the user approaches the boundary or geofence around the construction site, and display the location of the user’s hardhat in block 508 to help the user remember to wear the hard hat upon entering the construction site. Means for performing the operations of block 512 may include the processor (e.g., 210, 212, 214, 216, 218, 260, 312, 410) and the trigger event module 428.

The processor then may present the determined location or locations of the object or objects of interest in the environment in response to a correlated trigger event in block 508 of the method 500 as described.

With reference to FIG. 5C, following the determination of the location or locations of the object or objects of interest in the environment in block 506 of the method 500, in operations 500 c the processor may receive an indication that the object or objects of interest has/have been relocated to a second location in the environment in block 520. In some embodiments, the computing device may determine that the object or objects of interest has been relocated, such as part of or in response to another scan of the environment. In some embodiments, the computing device may receive information from the object or objects of interest indicating that the location of the object or objects of interest has been relocated, such as location information determined and transmitted by the object or objects (e.g., Global Positioning Information (GPS) information). In some embodiments, the computing device may receive the indication that the object or objects of interest has/have been relocated to a second location in the environment directly from a second computing device (e.g., from the second computing device 140 via communication link 115) or via an intermediary device (e.g., via network element 110). In some embodiments, the indication that the object or objects of interest has/have been relocated to a second location in the environment may be in the form of grid or mesh points within the map (e.g., generated in block 502) at or within which the object or objects of interest are now located. Means for performing the operations of block 520 may include the processor (e.g., 210, 212, 214, 216, 218, 260, 312, 410) and the object location module 426.

For example, a first computing device may determine that a first user put her car keys (designated as an object or objects of interest) down in a first location. Later, a second computing device (e.g., operated or worn by a second user) may determine that the car keys have been moved to a second location (e.g., the second user picked up and moved the keys). In some embodiments, the first computing device may receive the indication that the object or objects of interest has been relocated to the second location in the environment via a “push” operation (e.g., the computing device 140, or the network element 110, may send a location update to the computing device 102 from time to time, in response to determining that the object or objects of interest has been relocated to the second location, etc.). In some embodiments, the first computing device may receive the indication that the object or objects of interest has been relocated to the second location in the environment via a “pull” operation (e.g., the computing device 140, or the network element 110, may provide the indication that the object or objects of interest has been relocated to the second location in response to a request from the first computing device 102 for the location of the object or objects of interest).

In block 522, the processor may present the second location of the object or objects of interest in the map generated by the first SLAM operation in response to a trigger event. For example, in response to determining the occurrence of a trigger event (e.g., a time trigger, such as 7:30 AM), the first computing device may present the second location (i.e., the current location, or the last-known location) of the car keys (the object or objects of interest) in the map generated by the first SLAM operation. In some embodiments, the computing device may present the second location by displaying a grid or mesh point on the map generated using the first SLAM operation where the object or objects of interest are located. Means for performing the operations of block 522 may include the processor (e.g., 210, 212, 214, 216, 218, 260, 312, 410), the trigger event module 428, and the location presentation module 430.

With reference to FIG. 5D, following receipt of an indication from a second computing device that the object or objects of interest has been relocated to a second location in the environment in block 520 of the method 500, in operations 500 d the processor may determine that a trigger event has occurred in block 530. As described herein, in various embodiments a trigger event for displaying the location of the object or objects of interest may be determined by the processor by any of receipt of a user input (e.g., a voice prompt, button push, touch screen interaction, etc.), recognition of a user behavior or action correlated to a specific object or objects of interest, recognition of a user behavior or action correlated to a specific object or objects of interest and to other conditions (e.g., time of day, day of week, weather conditions, etc.), and/or recognition of a user behavior or action correlated to a specific object or objects of interest (and optionally other conditions) and determination that one or more of the correlated objects of interest are not with the user. Means for performing the operations of block 520 may include the processor (e.g., 210, 212, 214, 216, 218, 260, 312, 410) and the trigger event module 428.

In determination block 532, the processor may determine whether the computing device is authorized to disclose the second location of the object or objects of interest. In some embodiments, the processor may determine whether an indication is stored in a memory of the computing device, in a memory of a network element (e.g., the network element 110), and/or the like indicating whether the computing devices authorized to disclose the second location of the object or objects of interest. Means for performing the operations of determination block 532 may include the processor (e.g., 210, 212, 214, 216, 218, 260, 312, 410) and the authorization module 434.

In response to determining that the computing device is authorized to disclose the location of the object or objects of interest (i.e., determination block 532 = “Yes”), the processor may present the second location of the object or objects of interest in block 534. As described with reference to block 508, the processor may present the second location of the object or objects of interest as an indication on a map generated by a first SLAM operation, as images of the object or objects rendered to align with the location on augmented reality display, and/or as a grid or mesh point on the map generated using the first SLAM operation where the object or objects of interest are located. Means for performing the operations of block 534 may include the processor (e.g., 210, 212, 214, 216, 218, 260, 312, 410), the output module 216, the output device 268, and the location presentation module 430.

In response to determining that the computing device is not authorized to disclose the location of the object or objects of interest (i.e., determination block 532 = “No”), the processor may present an indication that the computing device is not authorized to disclose the second location of the object or objects of interest in block 536. Means for performing the operations of block 534 may include the processor (e.g., 210, 212, 214, 216, 218, 260, 312, 410), the output module 216, the output device 268, and the location presentation module 430.
